TG&V is shorthand for ‘tongue and groove with a v-joint’. TG&V cladding is a machined profile supplied with a smooth finish and an interlocking edge detail to create a waterproof façade. The TG&V profile creates a clean linear appearance which is ideal for contemporary new-builds and modern extensions to older properties. TG&V cladding is most commonly fixed horizontally although it can be fixed vertically.

All air-dried species can be machined to TG&V. The most popular choices are Siberian larch and Canadian western red cedar.

How to fix

VTG1, VTG2 – face fix only. One per fixing board / batten
VTG3, VTG4A, VTG5A, VTG6 – secret nail or face fix. One per fixing board / batten
A gap of 2mm should be left between each board

Horizontal attachment
Begin at the bottom, ensuring that the first board is level with the grooved edge facing downwards. If the width of the board is 150mm or less, it can be attached with a hidden nail diagonally through the tongue.For widths over 150mm, the board should be face-fixed, using two (nails?) per board. Fixings should be spaced 65 –75mm apart to allow for some dimensional movement.Vertical attachmentBegin at one corner, with the tongue facing away, ensuring that the first board is vertical. Nail as with the horizontal attachment.

Special or bespoke profiles up to 200mm wide can be provided. However, for external cladding, it is generally recommended that boards do not exceed 150mm in width.
